Company Info ▶Business Contents
① Matching App "with"
"with" is a dating and marriage matching app that was launched in September 2015 and allows users to match based on their values. It aims to be a service that allows users to find the best partner for themselves through statistics and psychology, and it has a "preference card" function that allows users to find a partner who has the same values as them, and a "psychological test" that allows users to match based on their deep psychology. The total number of members to date has exceeded 10 million (as of February 2024).

② Matching App "Omiai"
"Omiai" is a matching app that supports men and women to meet, which began providing services in Japan in February 2012 against the backdrop of social issues such as a declining marriage rate and a declining birthrate. Since the service began, it has been supported by many men and women looking for a date, and the total number of members has exceeded 10 million (as of July 2024). We will continue to operate our services in a way that is close to our customers so that we can continue to contribute to many people's search for happiness.
